Thermoseal Group urges IGU manufacturers to ensure compliance as OPSS ramps up inspections across the glass and glazing sector.

Part of the Department for Business and Trade, the OPSS is the UK’s national product regulator. Designed to ‘protect people and places from product-related harm by ensuring the safety and integrity of goods’, it enforces a wide range of regulations across the lifecycle of products, including those related to the construction and energy efficiency sectors. 

With heat soaked thermally toughened glass currently under particular scrutiny, the Glass and Glazing Federation (GGF) reports that the OPSS is conducting detailed inspections into manufacturers’ entire production processes. This includes Factory Production Controls (FPC), Declarations of Performance (DoP) and compliance with CE and UKCA markings.

“The focus is on heat soaking at the moment, but that could change at any point – and if your components are faulty, your units could be caught out,” said Thermoseal Group’s Sales Director, Mark Hickox. 

“Our customers have nothing to worry about, because we have full traceability and test data for all of our products, and indeed, the vast majority of our products are manufactured right here, in-house in the UK. 

“That means that we have full control over our products, ensuring that they fully comply with all relevant regulations. If you source your components elsewhere, and your current supplier can’t say the same, you might want to give us a call,” he added. 

The specialist IG component maker and distributor extensively tests all its products in-house at its EN1279 test facility, strengthening its credibility as a trusted product provider.

According to the most recent test results from IFT Rosenheim, the European notified and internationally accredited certification body, Thermoseal Group’s Thermoflex is currently the best performing flexible silicone rubber spacer bar in the world. This is also approved by the British Fenestration Rating Council (BFRC) in the UK, further evidencing the high quality of Thermoseal Group’s warm edge products. 

“During the R&D phase, we test our products thoroughly to ensure that they perform as intended, in full compatibility with other products in a complete unit,” added Mark. 

“This helps to raise the bar for quality assurance in the wider industry and gives our customers total confidence in the components we provide. Customers can also download full certification for every product on our website, for added peace of mind,” added Mark.
